My wife and I are flying from BKK to SYD next year in first class on an A340-600. I made the booking through Krisflyer but I did get the Thai airways reservation code. I have been into the TG site to check my booking and to choose my food but I can not find anywhere to select the seats. Am I blind or is this option not available? Perhaps I am just used to the easy seat selection on SQ. As you can guess this is my first time flying TG. Thanks in advance.
